IPC: F23D1/02
Filed: 1983-03-11
Abstract: PURPOSE:To contrive to reduce NOx by a structure wherein stainless steel members treated by cementation are arranged in a vertical flame cylinder and/or a horizontal flame cylinder. CONSTITUTION:A large number of stainless steel members 17 and 17', which are treated by cementation, are arranged in a flame cylinder connecting between a first stage combustion chamber 1 and a second stage combustion chamber 11 or a vertical flame cylinder 16 and a horizontal flame cylinder 10. NOx is produced by high temperature hollow flame due to incomplete combustion in the cyclone combustion chamber 1. However, the NOx contained in a gas, which is produced during first stage combustion in reducing atmosphere, is almost completely reduced due to the catalytic function of cementation treated stainless steel while passing through the vertical flame cylinder 16 and the horizontal flame cylinder 10. Accordingly, the quantity of NOx produced in the high temperature second stage combustion chamber 11 or in second stage combustion is reduced. Consequently, the reduction of NOx in exhaust gas can be resulted.

Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent solidification of ammonium thiocyanate during storage by drying a ammonium thiocyanate crystal to decrease the water content and then housing the crystal in a bag comprising a bag having specified permeability of water vapor and a craft paper bag. SOLUTION: An ammonium thiocyanate crystal prepared by crystallization is dried to decrease the water content to <=0.5%. The dried ammonium thiocyanate crystal is housed and stored in a bag comprising a bag having <=10g/m<2> .24Hr permeability of water vapor and a craft paper bag. The bag having specified permeability of water vapor consists of a composite film bag or a laminated bag of an Al foil and a moisture-preventing film.
